“…The transmission of infrared light reached the surface of the aluminum powder, which was reflected by the aluminum powder and absorbed by the black paste. The color of the coating increased the infrared emissivity [17]. When the content of black paste was less than 3.0%, the coating had lower infrared emissivity.…”

A fluorine resin/aluminum infrared coating was prepared with aluminum using black paste as filler and fluorine resin as binder. The effect of the black paste content on the performance of gloss, color difference, infrared emissivity, hardness, adhesion, impact resistance, roughness, optical testing, and corrosion resistance of the fluorine resin/aluminum infrared coating were examined. When the content of black paste was increased from 1.0% to 9.0%, the gloss of the coating surface decreased; the ΔE* value of the coating decreased; the infrared emissivity of the coating surface increased gradually; the hardness of the coating was 6H; the adhesion grade of the coating was 0; the infrared absorption peak increased gradually. When the content of black paste was 0%–3.0%, the impact resistance was more than 50 kg∙cm, and the impact resistance was higher. When the content of black paste was 0%–5.0%, the surface roughness of the coating was relatively low. When the content of black paste was 1.0%, the corrosion resistance of the coating was the best. The results showed that when the content of black paste was 1.0%, the performance of the whole fluorine resin coating was the best. Through the preparation and characterization of fluorine resin infrared low-emissivity coatings, the possibility of applying fluorine resin to infrared low-emissivity anticorrosive coatings was discussed, which laid a foundation for the subsequent engineering application of coatings.

“…The comparison results are shown in Figure (detailed optical properties have been summarized in Table S1). ,,− Also, the camouflage properties of metal and semiconductor films are placed in the picture for contrast. It can be seen that our result is found to be superior to that of reported works with the lowest IR emissivity and lowest visible reflectivity.…”

Multispectral camouflage technology against advanced detection has attracted rising attention in recent years. However, compatible camouflage with low visibility and low thermal emission in a dark background still remains challenging (such as satellites, high-altitude planes, etc.). In this work, a low visibility and low thermal emission nanostructured film with electromagnetic band gap for multispectral camouflage is proposed. The structure demonstrates a Ge/ZnS multilayer for suppressing thermal emission, which is mounted with nanolayered dielectric antireflection stacks to absorb visible light. Also, the all-dielectric configuration ensures microwave transmission for being compatible with microwave camouflage. The fabricated structure shows low reflectance (3.95%) for 300–1100 nm visible-near-IR light, low emissivity for 3–5 μm (0.043) and 8–14 μm (0.093) atmospheric window ranges, and high transmittance (98.86%) for 8–18 GHz microwave range. Moreover, the film exhibits low lightness and suppressed thermal radiation signatures with incident angles up to 60°. The proposed nanostructured Ge/ZnS film paves the way for multispectral camouflage and other applications such as solar–thermal conversion, radiation control, and optical sensing based on electromagnetic wave manipulation.

“…They not only have the high-temperature resistance and good chemical stability of ordinary ceramic coatings but also have an excellent radiation and heat dissipation capacity. They have been favoured by researchers because of these advantages and are now widely used in metallurgical manufacturing, aerospace, architectural coatings, and several other technical fields [4][5][6][7].…”

High-emissivity coatings are often used on the surfaces of solar probes to block heat from the sun. Therefore, improving the thermal control ability is the standard for determining the quality of the coatings. In this study, MgO was doped into Al2O3 to improve the thermal control ability of the coatings and to analyse the effect of different MgO doping contents. The solar absorptivity to infrared (IR) emissivity ratio (α/ε) was used to evaluate the thermal control ability of the coatings. The results showed that 5 wt.% MgO doping content is the best choice. The main reason for the change in α/ε is related to the doping of MgO, which affects the grain size of Al2O3.
